To all whom it may concern:

Be it known that I, Lnwrs E. IVATERMAN, a citizen of the United States,residing at Rockford, in the county of IVinnebagO, Illinois, haveinvented certain new' and useful Improvements in Disk Harrows, of whichthe following is a specification.

The object of this invention is to 'form the support for the teeth witha tubular extension around which is placed one end of a scraper, and aspool located between two disks, one end of which holds the end of thescraper from movement in the lengthwise direction of the gang.

In the accompanyingl drawings. Figure 1 is a lengthwise vertical sectionthrough some of the disks of a gang, the main frame and some other partsnot being sectioned. Fig. 2 is a partial face view of the main portionof the disk, and the connection of a scraper with the tubular portionextending from the disk.

Each of the disks l have a tubular hub 2 extendingl from the face plate3. In forming up a gang of the disks a rectangular rod 4 is placed inthe rectangular opening 5 of each disk. Between two disks on the rod 4is located a spool 6 having enlarged heads 7 and S. The head 7 of aspool rests in contact with the end of the hub 2 of a disk, and theother head S rests in contact with the inner face of the plate 3 asshown at Fig. The brackets 9 have their lower ends 10 in box form andeach receives a spool. These brackets serve to support the main frame 11of the gang and serve to hold the rectangular rod 4 in proper alinementto connect all the disks of a gang.

To the main frame 11 are connected scrapers 12 one for each disk. Thelower end of each scraper is located around the hub `2 of a disk, andagainst the plate 3 of the disk and the end 7 of a spool 6, which servesto hold the scraper from movement in the lengthwise direction of thegang, that is, the scraper is heldv in proper relation with the disk tothrow off any accumulations that may be picked up by the teeth.

I claim as my invention.

A harrow section comprising a main frame, a rod, brackets connected tothe frame and to the rod, a series of disks having the rod located intheir axial center and having a hub extending therefrom, a series ofspools, one located between two disks one end of a spool resting incontact with the hub of a disk, and a scraper for each disk having oneend encirclingl the hub of a disk and held against displacement by theend of the spool.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
